DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a hinge structure of a door according to the present invention will be described.
An embodiment will be described with reference to FIGS. As exemplified in reference FIG. 1 showing a cross section perpendicular to the pivot axis of the hinge structure,
In this embodiment, a movable member 1 connected to a door front plate 12 and a fixed member 2 connected to a fixed member such as a box body.
Are formed by a combination of the above two members.

Here, the movable side member 1 is integrally provided with a cylindrical rotating shaft body 11 in which a part of a ring is cut out, and has a resilient structure capable of expanding the outer diameter. By inserting the expansion member 22 into the central space, the expansion member 22 is held in an expanded state as described later, and is fitted into the next cylindrical bearing body 21. On the other hand, the fixed side member 2 is integrally provided with a cylindrical bearing body 21 for rotatably fitting and supporting the rotating shaft body 11 of the movable side member 1. When the rotation shaft 11 rotates, a part of the cylindrical body is cut out so as not to hinder the movement of the door front plate 12 connected thereto.

The movable member 1 is provided with a pair of arc-shaped reinforcing projections 13a and 13b on both sides of the rotating shaft 11 so as to surround the rotating shaft 11. The cylindrical bearing body 21 is slidably held between the reinforcing protrusion 13 a or 13 b and the rotating shaft 11.

In this case, when the movable side member 1 is in a closed state, as shown in FIG. 1, an inner reinforcing projection 13b connects one of the cylindrical bearing members 21 with the rotating shaft body 11. 2, when the movable member 1 is open, the outer reinforcing projection 13 a is mainly disposed between the rotary shaft 11 and the other end of the cylindrical bearing 21, as shown in FIG. 2. They are arranged to function alternately so as to sandwich them.

In such a hinge structure of the door, the rotating shaft 11 of the movable member 1 before being fitted to the fixed member 2 is used.
As shown in FIG. 3, the diameter is slightly smaller than the inner diameter of the cylindrical bearing body 21 and is formed in a ring-shaped elastic structure with a part cut away. Then, it is fixed to the fixed member 2
After being fitted into the cylindrical bearing body 21, as shown in FIGS. The outer diameter of the fitting is adjusted by inserting and attaching the fitting so that the fitting is appropriately pressed against the cylindrical bearing body 21.

Further, in the present invention, the rotating shaft 11 connected to the movable member 1 connected to the door is fitted to the cylindrical bearing 21 of the fixed member 2 and is supported rotatably. At the same time, reinforcing protrusions 13a provided on both sides of the rotating shaft body 11,
Since at least one of the movable members 13b is always engaged with the cylindrical bearing member 21 in a state of being sandwiched therebetween, the movable member 1 and the fixed member 2 rotate around the rotating shaft 11 as an axis. The opening and closing operation of the door connected to the movable member 1 can be performed,
Moreover, the joining strength of the two members 1 and 2 is improved so that they are not easily separated.

As described above, the expanded rotating shaft 11 is configured to sandwich the cylindrical bearing 21 so as to be slidable at a preferable pressure between the pair of arc-shaped reinforcing protrusions 13a and 13b. As a result, the assembling accuracy is improved, and the engagement strength between the movable member 1 and the fixed member 2 can be increased.

Referring to FIG. 4, an embodiment in which such a configuration is further embodied will be described. The pivot shaft 11 of the movable member 1 having the door front plate member 12 connected thereto is fitted to a fixed member (not shown). Then, a top plate (not shown) and a bottom plate 3 that cover the end surfaces of the door front plate 12 and the movable member 1 are attached, and the rotating shaft 11 is provided from outside the top plate (not shown) and the bottom plate 3. The screw 31 which is an expansion member is screwed into the center space of, and the outer diameter of the rotating shaft body 11 is expanded, and the top plate (not shown) and the bottom plate 3 are assembled.

According to the hinge structure of the door of the present invention, in particular, since the rotating shaft is formed of an elastic structure capable of expanding the outer diameter, the rotating shaft is formed into a small diameter in advance.
A hinge structure of a door can be provided which facilitates the fitting operation and, at the same time, expands the outer diameter by inserting an expansion member into the rotating shaft after the combination to increase the assembly accuracy. Also, when attaching the top plate material or the bottom plate material arranged above and below the door, the outer diameter of the rotating shaft body is expanded by an expanding member which also serves as a mounting hardware, and is fitted to the fixed side member and assembled, so that the door is assembled. This also has the advantage that the number of assembly steps can be reduced.

In this embodiment, the cross-sectional shape of the rotating shaft body is a partially cut-out ring shape. However, any shape may be used as long as it has an elastic structure that meets the above-mentioned purpose. There may be no simple hollow ring shape.

[0016]

Since the hinge structure of the present invention is constructed as described above, it can be easily manufactured by extruding a material such as an aluminum alloy using a predetermined mold. It is possible to easily assemble a hinge structure by fitting such a movable side member and a fixed side member and pushing one into the other, so that the number of mounting steps can be greatly reduced. . Further, since the rotating shaft body is formed of an elastic structure capable of expanding the outer diameter, the rotating shaft body is formed into a small diameter, the above-mentioned fitting and pushing operation is easily performed, and after the combination, the expanding member is expanded. The excellent effect that the insertion precision can be increased by assembling to increase the assembly accuracy is obtained. Therefore, the present invention has a very large industrial value as a door hinge structure which solves the conventional problems.
